Application filed August 1, 1917. Serial No. 183,876.

To all whom it may concern:

Be it known that I, PAUL DE CHIME, a citizen of the United States,residing at Youngstown, Mahoning county, and State of Ohio, haveinvented a new Strainer for Pump-Wells, of which the following is afull, clear, and exact description.

My invention relates generally to strainers and more particularly tostrainers for use on hand pumps for use in pumping water from wells.

One object of the invention is to provide a strainer which can bereadily attached to pumps of various sizes. Another object is to providea novel strainer which will allow the pure water to pass through afilter or screen and require the impurities to pass out through alateral waste passage, thus keeping the main water passage clean andsanitary.

With these general objects in View, my invention will be best understoodupon reference to the following description taken in connection with theaccompanying drawings and the scope of the invention will be pointed outin the appended claim.

In said drawings, Figure 1 is a perspective view of a strainerconstructed in ac cordance with my invention shown applied to a pump;Fig. 2 is partial sectional elevation of the strainer detached from thepump; and Fig. 3 is a perspective of the nipple located at the lower endof the strainer. Throughout these views like characters refer to likeparts.

Referring to the drawing in detail, F designates the tubular casingwhich is adapted to fit at its upper end over the spout of the pump. Abolt B threaded through an opening in said casing engages the pump spoutand serves to securely hold the easing on the pump. Near its lower end,the casing is provided with a laterally and downwardly extending funnelshaped portion T which has a small waste outlet at its lower end. Theportion T is connected with the casing F by an elbow N. A nipple Wpreferably of wood is inserted into the lower end of the tubular casingF and is provided with a fine wire screen or filter S. When the nippleis in assembled position, the screen lies adjacent to the elbow N and insuch a position that all the impurities arrested by the screen S passinto the lateral funnel shaped portion T and out through the wasteoutlet at its lower end. The entire device is clean and sanitary andwill remain operative in all kinds of weather, in striking contrast tothose cases where cloth and rubber are used for filtering.

I claim:

A strainer for hand pump for Wells comprising a unitary tubularv casingconsisting of a main portion and an auxiliary waste portion, said mainportion being open at its upper end so as to fit over the spout of thepump and being open at its lower end so as to provide an outlet for thewater, a nipple of wood located in the outlet of said main portion, saidwaste portion extending from a point near the lower end of said mainportion laterally and downwardly beyond the lower end of said nipple andhaving a waste outlet at its lower end permanently open and incommunication with the interior of said main portion, a screen upon theinner end of said nipple located at the inlet to said waste portion sothat the passage of water through said Waste portion will carry theimpurities arrested by said screen out through said waste outlet, and asecuring bolt passing through a threaded opening in said easing intocontact with the pump spout.
